DNV GL progresses offshore pipelay codes program

Offshore staff

ABERDEEN, UK – Aquatic Engineering & Construction is assisting DNV GL and other subsea organizations on guidelines for “The Development of Codes for Offshore Equipment for Cable and Pipe Laying – Phase 1.”

These will be incorporated into new or existing DNV GL offshore standards or recommended practices.

David Tibbetts, vice president technology at Aquatic, said: “We were eager to get involved with this ground-breaking project due to the lack of coherent standards for the specification, design, manufacture, procurement, and approval of equipment intended for use in offshore cable and pipelaying operations…

“The work involves engineering and technical experts from contractors and equipment manufacturers like Aquatic, collaborating in order to establish joint industry guidelines for our type of equipment, where at present nothing exists. Subject to satisfactory completion of the first two phases, a third phase undertaken by DNV GL will result in the publication of an offshore standard or recommend practice for cable/pipelaying equipment.”

DNV GL initially issued proposals in November 2014 that comprised:

  • Phase 1: Mapping the Big Picture. The aim is to provide a common, system-level understanding of equipment required for successful installation of cables and pipes.
  • Phase 2: Mapping the Detail. This is intended to focus on individual system components, identifying their inputs, outputs, and interaction with other components.
  • Phase 3: Following completion of phases 1 and 2 this year, creation of guidelines and a glossary of common terms for cable and pipelaying equipment. A third phase could follow that would lead to publication of a DNV GL standard for certification or recommended practice.

Dr.-Eng Marius Popa, lead naval architect, DNV GL, said: “Consistency and collaboration within the industry is essential. Individual practices create unnecessary cost and risk, so the development of a unified approach will ensure standardization across the supply chain. The JIP will deliver a decision tool that can be used by all stakeholders during the specification, design, manufacture, procurement, and approval of any equipment intended for use in offshore cable/pipelaying and recovery.”

Other Phase 1 participants are Allseas Engineering; Amclyde Norson Engineering; IHC Engineering Business; IHC SAS; MAATS Tech; NLI Offshore & Marine Products; Parkburn Precision Handling Systems; Reel SAS (IMECA); Saipem Group; Subsea 7; and Technip UK.
