Service Introduction

Longitude’s ship design process embodies a design with experience approach – as the design house of global consultancy ABL Group, we possess unrivalled access to practical experience across offshore energy installation and maintenance campaigns.

Blended with our long-standing ship design expertise, we deliver design and engineering solutions for offshore vessels, which are fit-for-purpose, reliable, efficient and tailored to a client’s specific requirements and those of the designated scenario in which the vessel will operate.

A recognised name in the design and engineering of offshore vessels, Longitude’s ship design portfolio includes expertise in platform supply vessels (PSVs), service operation vessels (SOVs), cable lay vessels, anchor handlers Emergency Response and Safety Standby, Seismic Support and Construction Support vessels and jack-ups.

With our parent company’s legacy dating back to the world’s first marine survey company, The Salvage Association, we further incorporate a long-standing understanding of offshore vessel performance, reliability, and potential failure modes, into our everyday design work. This historical perspective informs design decisions, leading to more robust and dependable vessels.

Finally, as an independent partner in ship design, we work closely with our clients and the stakeholders along the design process, to deliver a bespoke design solution that will deliver value and operational success.

Offshore Vessel Market Challenges

High demand for SOVs and PSVs in an increasingly congested offshore energy space
Offshore vessel designs that are operationally fit-for-purpose or have the flexibility to be adapted to suit its destined operations
Adaptability for future decarbonisation and alternative fuel technology
Local Flag requirements and barriers in certain markets like the Jones Act in the USA
Technological upgrades are required to accommodate larger assets as offshore wind projects become larger, more powerful and move to deeper waters

With an ever-expanding and in-demand offshore energy industry, clients require offshore vessel designs which they can trust to perform. By that we mean, designs which are:

Reliable and with optimum efficiency
Compliant with the latest regulatory standards, or flexible to be adapted to meet new requirements
Optimised for real-world operations, with a safety-first approach, minimising downtime, and maximising profit
Adaptable to incorporate the latest innovations, alternative fuel applications and for enhanced performance throughout an asset’s lifecycle
