Whether you're planning a temporary offshore mobilisation, installing mission equipment for a subsea campaign, or executing a full offshore vessel conversion, GLO Marine provides the complete vessel-side engineering package — from feasibility and structural design to class approval, installation, and commissioning.
We support offshore vessel mobilization, offshore mobilization, PSV conversion, OSV conversion, and retrofit offshore solutions across the North Sea, West Africa, Middle East, and Asia-Pacific.
GLO Marine proved to be an adaptive, cooperative, and solution-focused partner.
The scope was well understood, though the Eurocode requirements were slightly underestimated.
What stood out was their open and transparent communication—challenges were identified early, discussed constructively, and resolved quickly. They adapted fast to the required standards, implemented new ideas efficiently, and maintained a high level of quality throughout. We see strong potential for future collaborations.
From temporary mobilisation equipment to permanent retrofit systems, GLO Marine delivers vessel-side integration engineering across all major offshore system types.
We develop the vessel-side engineering for ROV installations — including structural foundations, moonpool modifications, tether management, and control system interfaces for work-class and observation ROVs.
OEMs: Oceaneering, Forum Energy, MacArtney
Launch and Recovery Systems require precise load-case analysis and structural integration. We deliver engineering packages for A-frame LARS, overboarding systems, and vertical lay systems up to 290t capacity.
OEMs: MacGregor, Huisman, Kongsberg
IMR campaigns require multi-system integration — winches, tooling containers, ROV spreads, and deployment systems — delivered as a coordinated engineering package.
We provide vessel-side engineering for Ampelmann and other gangway systems, including stability analysis, deck reinforcement, and HPU/control interfaces.
OEMs: Ampelmann, Uptime, TMS, Barge Master
Engineering for PTB installations including crane interface design, structural attachments, and IMO compliance.
We design structural tie-downs, fire and gas interfaces, and SPS-compliant integration for temporary accommodation units.
Temporary or permanent mezzanine decks for equipment storage, diving systems, and expanded workspace.
We design pedestal foundations, deck reinforcements, and hydraulic/electrical interfaces for offshore cranes.
OEMs: Heila, Techcrane, NOV
Engineering for cable-laying vessels including turntable foundations and stability analysis for heavy carousel systems.
Integration of containerised campaign systems including skids, labs, and subsea tooling.
We design switchboard upgrades, power distribution, and PMS interfaces required for system integrations.
Mobilisation engineering
Temporary campaign equipment installed onboard, typically delivered within short timeframes. The vessel is prepared for a specific operation and can return to its base configuration after completion. The focus is on speed, integration, and execution within a defined mobilisation window.
Conversion engineering
Permanent modifications that change the vessel’s operational profile. This includes structural upgrades, stability changes, and new system integration for long-term use. The focus is on durability, compliance, and expanded capability.
Our mobilisation and integration process is structured to minimise engineering iterations, compress lead times, and eliminate surprises at the yard.
We assess vessel structural reserves, stability margins, and deck capacity against the target system's requirements. You receive a concise feasibility note within days — not weeks.
Structural drawings, foundation calculations, stability booklet updates, and class submission documents — all delivered as a single coordinated package. No gaps between disciplines.
We liaise with DNV, Lloyd's Register, Bureau Veritas, and other class societies on your behalf — managing comments, revisions, and approval milestones to your project schedule.
Mobilisation begins with validating vessel fundamentals: structural capacity, stability margins, and integration feasibility.
Core disciplines:
Naval architecture
These disciplines form the foundation for safe, class-compliant offshore vessel mobilisation and system integration.
Practical answers to the questions that arise when planning offshore vessel mobilisation projects — from feasibility and timelines to interfaces and delivery risk. If you’re working against a mobilisation window, we can review your vessel and system directly.
That depends on structural capacity, stability margins, available deck space, and existing systems onboard.
We typically assess:
We can provide a feasibility assessment within days, identifying whether the installation is viable and what modifications are required before committing to detailed engineering.
Delays are rarely caused by core engineering — they come from interface gaps.
Typical issues include:
Our approach eliminates these by managing engineering, vendor coordination, and Class liaison under one scope, so interfaces are resolved early — not during installation.
Yes — and that’s a critical part of our role.
We regularly coordinate with OEMs such as:
We take ownership of the vessel-side interface engineering, ensuring alignment on:
This reduces rework and shortens approval cycles.
For most mobilisation scopes:
The biggest variable is not engineering — it’s how early Class and OEM inputs are aligned.
We engage Class (DNV, BV, Lloyd’s, etc.) early and manage submissions directly to keep timelines predictable.
We do.
Because we deliver:
If something doesn’t fit or align during installation, it’s our scope to resolve it, not a gap between contractors.
This is one of the main reasons clients use a single integration partner instead of multiple parties.
Both — but most projects start as mobilisation.
We support:
The engineering approach is consistent, but conversion projects involve deeper structural and regulatory scope.
With tight mobilisation windows, Class requirements, and multiple system interfaces, early engineering alignment reduces delays, rework, and execution risk.
