Complete marine, diving
& fabrication solutions

Close Visual (CVI) and General Visual (GVI) inspections supported by live HD surface monitoring and time-stamped video recording. Ultrasonic Thickness (UT) gauging, Magnetic Particle Inspection (MPI), and Cathodic Protection (CP) surveys. Pier scour assessments, caisson inspections, intake and outfall pipe inspections, dock wall integrity checks, and UWILD class surveys for commercial vessels.

Underwater concrete formwork, tremie pours, grout bag placement, and structural underpinning. Scour protection, subsea drilling, cofferdam installation, and pile positioning. Oxy-arc cutting, specialised wet welding, pneumatic breaking, and mechanical demolition for heavy modification or removal.

High-pressure hydro-jetting, airlift/dredging, and pipe plugging or blanking. Subsea valve servicing, seal and structural bolt replacement, and sacrificial anode retrofits. Vessel maintenance including emergency propeller entanglement clearing and underwater coating applications.

A 24/7 emergency call-out team, deployed rapidly for structural failures, critical pipe blockages, vessel entanglements, and marine salvage operations — with full rigging and heavy-lift support for asset recovery.

Repair of spalling, cracked, and degraded quay wall concrete caps, cope beams, and deck edges damaged by marine salt exposure, freeze-thaw cycles, or heavy vessel impacts.

Reinforcement and restoration of corroded or structurally compromised steel H-piles and sheet pile retaining walls across tidal and splash zones.

Supply, crafting, and fitting of heavy-duty timber fendering systems designed to absorb vessel kinetic energy and protect primary quay structures, specialising in dense marine hardwoods including Greenheart and Ekki (Lophira alata).

Installation, realignment, and servicing of commercial rubber fendering configurations, including continuous 300mm section D-fenders across extensive berth lengths (300m+ sections), as well as arch, cone, and cylindrical profiles.

Heavy-duty steel infrastructure including tubular piles, waling beams, pile caps, mooring bollard plates, walkway gantries, and access ladders tailored for port facilities and coastal developments.

Bespoke steel backing plates, mounting brackets, transition pieces, wear plates, spud poles, and tie-back assemblies designed to integrate directly with concrete, timber, or sheet-pile quay structures.

Field modifications, structural erection, and rapid repairs using MIG/MAG and MMA welding techniques, backed by crane and barge logistics and supported by mobile site teams.

Rigorous surface protection for extreme salinity, including Sa 2.5 grit blasting, hot-dip galvanizing, and multi-coat C5-M marine epoxy paint systems built for long-term splash zone protection.

Complete submerged and topside component maintenance — inspecting, servicing, and replacing heavy ground tackle including sinker weight blocks, marine swivel shackles, and high-tensile mooring chains, alongside servicing top-side navigation lanterns, solar battery systems, and radar reflectors.

Complete seasonal management programmes for coastal local authorities, ports, and beach operations. Having placed, recovered, and stored out-of-season swim and boat lane marker buoys for Brighton and Hove for over 15 years, we offer a turn-key solution covering autumn recovery, secure winter shore-storage, full blast-cleaning and re-painting, and precise spring re-deployment.

Using specialised work vessels like the M.V. Valkyrie with onboard crane and A-frame handling capabilities, we recover damaged, adrift, or degraded buoys directly from marine sites — handling large-scale marker buoys up to 4–5 metres in height and diameter, with unit weights reaching up to 2 tonnes.
