Slow steaming and regulatory drive toward more energy efficient ships have raised a problem of ensuring sufficient maneuverability of ships under adverse weather conditions when installed power is reduced. This paper discusses possible criteria for maneuverability in adverse conditions, proposes practical assessment procedure, and shows examples of its application. Further, the paper outlines necessary developments. © 2017 by ASME.

Whipping/springing research started in the 50’ies. In the 60’ies inland water vessels design rules became stricter due to whipping/springing. The research during the 70-90’ies may be regarded as academic. In 2000 a large ore carrier was strengthened due to severe cracking from North Atlantic operation, and whipping/springing contributed to half of the fatigue damage. Measurement campaigns on blunt and slender vessels were initiated. A few blunt ships were designed to account for whipping/springing. Based on the measurements, the focus shifted from fatigue to extreme loading. In 2005 model tests of a 4,400 TEU container vessel included extreme whipping scenarios. In 2007 the 4400 TEU vessel MSC Napoli broke in two under similar conditions. In 2009 model tests of an 8,600 TEU container vessel container vessel included extreme whipping scenarios. In 2013 the 8,100 TEU vessel MOL COMFORT broke in two under similar conditions. Several classification societies have published voluntary guidelines, which have been used to include whipping/springing in the design of several container vessels. This paper covers results from model tests and full scale measurements used as background for the DNV Legacy guideline. Uncertainties are discussed and recommendations are given in order to obtain useful data. Whipping/springing is no longer academic. © 2014, Society of Naval Architects of Korea.

Industrial sites seeking energy improvements must have a means of identifying prospective projects. Upon starting a program of energy efficiency, a site typically progresses through methods that easily find prospects and takes on increasingly more difficult identification methods as the energy efficiency program matures. Four types of project identification are addressed in order of increasing difficulty.

Ti-clad steel welded joints made with different interlayer material-joining process combinations were evaluated using microhardness, bend, and shear-bond strength testing. The effect of thermal cycling on the shear-bond strength was evaluated as well. In general, all the welded joints present the highest hardness level at the interlayer-Ti interface and across the first Ti layer. The maximum hardness in welded joints made with the Ni-Ti, NiCu-Ti, and NiCr-Ti interlayer systems was 607,568, and 554 HV0.5, respectively. In the V-Ti and Ti-V systems, the respective maximum hardnesses were 307 and 409 HV0.5, respectively, at the Fe-V interface. The maximum hardness observed in welded joints made with the Cu-Ti interlayer ranged from 300 to 350 HV0.5. Different softening responses to either thermal cycles of additional Ti layers or PWHT were observed in different types of joints. Most of the joints failed the bend tests in the as-welded and PWHTed conditions. The Ni-Ti-, NiCu-Ti-, and NiCr-Ti-welded joints failed along the interlayer-Ti interface and through the Ti weld layers. The Cu-Ti welded joints made with the CSC-GMAW process failed along the Cu-Ti interface. The bond-shear strength of both Fe-Cu and Cu-Ti interfaces in Cu-Ti welded joints made with a combination of CSC-GMAW and GTAW-P processes in the as-welded, PWHTed, and thermally cycled conditions ranged from 204.5 to 259.8 MPa (29.6 to 37.6 ksi). The Fe-Cu interface showed a larger displacement under maximum load as compared to that observed in the Cu-Ti interface.

NACE - International Corrosion Conference Series | Year: 2016

Galvele introduced a new quantitative framework for localized corrosion through his seminal paper on acidification and chloride accumulation in pits and the need for a critical product of current density and pit depth to sustain this local chemistry. This concept, introduced in 1976, holds good today, but has been enhanced by the ability to conduct more complex computations, better modeling of concentrated solutions that could be present in local areas, and the ability to perform in-situ chemical analyses in pits. The purpose of this paper is to review the progress in these areas with a particular focus on the relationship between localized chemistry and repassivation potential. The paper discusses the results of different reactive-Transport modeling approaches in understanding local chemistry changes during repassivation, and the use of different in-situ chemical analyses in understanding localized corrosion. © 2016 by NACE International.

A detailed study is described of the post-yield behaviour of four medium-plastioity heavily over-consolidated UK stiff clays. Sub-layers of the stiff-to-hard Gault, Kimmeridge and Oxford clays were identified, sampled and tested; these, along with fades investigated in an earlier London Clay study, had broadly similar depositional histories. The intention in considering a spread of similar sediments from the Jurassic to the Eocene was to allow any strong effects of geological age, or burial depth, to be identified. A strongly fissured meso-structure was present in three of the four clays, which had a controlling influence on their effective shear strengths, considering that the representative element volume is of paramount importance in measuring the strengths of such soils. All four soils were brittle in shear and, when sheared to sufficient displacements, developed low residual shear strengths. The stiff clays were investigated further through comparisons between natural and reconstituted behaviour, using the latter to normalise the effective stress data for volume and also considering the clays' oedometer swell sensitivities, Normal compression tests, when normalised for void index, implied different degrees of ‘structure’ than undrained shear tests, showing that a more elaborate micro- and meso-fabric framework is needed to capture the behaviour of highly overconsolidated and aged geomaterials. This paper focuses on describing the study sites’ geotechnical profiles and the stiff clays' yielding behaviours under one-dimensional compression and in triaxial compressive shear. © 2014, (publisher).

Proceedings of the International Offshore and Polar Engineering Conference | Year: 2016

DNV GL along with Ultra Deep launched a Joint Industry Project (JIP) to validate the loxodromic assumption, i.e. slip is assumed to occur in axial helix direction only, in bending stress calculation used in local analysis of umbilicals and flexible pipes. The validation is performed by comparison of the numerical model described by Skeie, Steinkjer and Sødahl (2010), hereafter called HELICA, with high quality bending tests, contributed to the JIP. Loxodromic assumption is increasingly used in the industry in local stress analysis of umbilicals and flexible risers. The results showed a remarkably good agreement between the stress calculations and the stress measurements, thereby confirming the validity of the loxodromic assumption. The accuracy in the prediction of umbilical steel tube stresses achieved also suggests that the largest uncertainty in fatigue prediction has moved from the stress assessment and back towards the global loads prediction. © Copyright 2016 by the International Society of Offshore and Polar Engineers (ISOPE).

Still years away from exploiting its own natural gas potential, Cyprus is now reviving efforts to nail down import options to help the country meet its climate targets through liquefied natural gas projects. According to media reports, Cyprus is preparing to launch a study into importing LNG to help meet the country’s domestic demand and ease the planned transition towards lower emissions power production. "The objective of the study is, based on the analysis of the various options of LNG supplies, to identify and propose an option/project, an appropriate process and a timetable for the supply of gas to Cyprus [as soon as possible] and before 2020," according to a tender released by state-owned Natural Gas Public Co. The utility expects bids for an LNG purchase tender from Gaffney, Cline & Associates, KPMG, Wood Mackenzie, DEP Levant Oil & Gas, DNVGL, Arntzen de Besche and Genesis Oil and Gas, according to the report. The tender comes after earlier efforts failed last year after relevant domestic agencies rejects a proposal from a firm that intended to sell about a third more natural gas than initially proposed. The import move comes despite some progress made towards developing local natural gas reserves as they are not expected to start producing for several years. Further, the country’s largest field has struggled to progress as financing has been difficult to nail down amid lower global pricing. Once the country can move its domestic production efforts closer to output completion, it will then face the possibility of export options to an eager European market and regional cooperation, including possible meeting points with Turkey. However, those challenges remain a long ways off for Nicosia and its local energy agencies. In the meantime, Nicosia is exploring options for meeting its natural gas demand, as well as meeting its goal of switching power generation to natural gas by 2018 and meeting broader, global climate goals agreed to in Paris earlier this year.
