Marine Fender Replacement at Jebel Ali Port | Rope Access Execution for Dubai Petroleum

Marine fender replacement using rope access was successfully executed by AIMMS Group for Dubai Petroleum at LNG Jetty Terminal 4, Jebel Ali Port. This critical project involved replacing large fenders over days schedule and highlighted our specialized capabilities in rope access and marine infrastructure maintenance. The operation was completed with a strong focus on safety, precision, and minimal disruption to ongoing port activities.

Project Overview

• Client: Dubai Petroleum

• Location: LNG Jetty Terminal 4, Jebel Ali Port (JAFZA)

• Support Vessel: DSV MAHARA

• Scope: Replacement of  marine fenders

• Team: 6 rope access technicians + 1 IRATA Level 3 Supervisor

• Support Equipment: Crane-assisted lifting, chain blocks, and vessel-based hoists

Why Marine Fender Replacement Matters

Marine fenders are vital for absorbing the kinetic energy of docking vessels and safeguarding both the port infrastructure and vessels. Over time, continuous impact, corrosion, and weather exposure degrade their performance. Dubai Petroleum identified the urgent need to replace fenders to ensure continued safe berthing for offshore support vessels.

Our Rope Access Strategy: Safe, Fast, Cost-Efficient

AIMMS Group opted for rope access methodology over conventional scaffolding or barge-based solutions to address the limited access space, tidal changes, and vessel traffic. This minimized operational disruption while ensuring crew safety and efficient execution for disruption.

Project Execution progress

Task 1 : Removal of Old Fenders

• Rope access technicians conducted safety briefings and installed rigging systems as per IRATA and HSE protocols.

• Using chain blocks and auxiliary hoists, the team began the careful dismantling of shackles and supporting components.

• Old fenders were unbolted, inspected, and safely lifted off using crane and vessel coordination.

Task 2 : Installation of New Fenders

• The new fenders were aligned and lowered into position using taglines, webbing slings, and precise crane maneuvering.

• Technicians secured upper and lower chain attachments, pad-eyes, and shackle points.

• After double-checking all bolted connections, the rigging was removed, and daily HSE documentation was submitted.

Key Safety and Technical Measures

• All personnel were IRATA certified and trained professionals.

• Tools and equipment followed ISO and IRATA standards, with double fall arrest systems, tool lanyards, and rope protectors.

• A fall proof rescue plan and exclusion zones were implemented.

• Daily toolbox talks, buddy checks, and PPE compliance were enforced throughout the operation.

Highlights from the Project

According to the approved method statement:

• Anchor points with a minimum load capacity of 15kN were used.

• Mechanical Advantage 6:1 hoist systems supported material movement and rescue readiness.

• Team were mobilized in short term notice.

• Executed the work with 100% safety.

Overcoming Challenges at Jebel Ali Port

Executing a marine fender replacement at a live port facility like LNG Jetty Terminal 4 presented multiple operational and environmental challenges — each of which required tailored solutions to maintain safety, schedule, and quality.

Limited Access & Tidal Conditions

The work zone was directly along the quay wall, with restricted horizontal access and no scaffolding options. Changing tides added complexity, as access height and safe working zones varied throughout the day. Rope access provided the agility and flexibility needed to work across shifting tidal levels.

Corroded Fittings and Hardware

Some of the existing shackles, pad-eyes, and fender chains were heavily corroded, requiring extra effort to clean, loosen, and safely dismantle them. Our technicians used rust remover, manual tools, and mechanical hoists to disassemble the rusted components while suspended on ropes.

Complex Lifting and Alignment

The replacement fenders were large, heavy units, requiring crane-assisted lifting in confined berthing spaces. Ensuring accurate alignment of the new fenders while suspended — and tightening bolts to manufacturer torque specifications — demanded both skill and coordination between the crane operator and rope access team.

Strict Safety Compliance in a High-Risk Zone

Working over water, at height, and with heavy loads meant every movement had to be meticulously planned and risk-assessed. Exclusion zones, double fall arrest systems, edge protection, and a rig-for-rescue plan were all mandatory and actively monitored by the IRATA Level 3 Supervisor.
