The reelers were each designed to accommodate a 2500m length of 78mm OD electro-hydraulic umbilical, and were based on a similar design that TIS had previously supplied multiple units of to the same client for project works in West Africa.

TIS Umbilical Reelers are designed to deploy and recover any length and diameter of umbilical product, with suitable controls to facilitate multiple hydraulic, chemical, electrical and fibre optic power and signal cores.

These Umbilical Reelers (TU-A-1044-3), certified in compliance with DNV-ST-E273 and CE ATEX Zone 1, were purpose built to suit the client specified umbilical’s cores comprised of nine hydraulic lines, two chemical line, two power cables (each with 30 conductors), and two data cables (each with four conductors). This topside control equipment is used for the client’s electro-hydraulic landing string, typically deployed as part of a system for subsea exploration and appraisal operations.

The units incorporated several features to protect both the umbilical and the operator. A traverse spooling head sub-assembly was designed specifically to suit the umbilical OD, with two stainless steel endless screws synchronising the distance the spooling head travels per rotation of the reel to provide perfect even wraps to the drum. The spooling system rotates around the top half of the drum to provide a 180⁰ range of horizontal and vertical spooling angles, allowing the client multiple options of where to site the reeler to for the deployment arrangement during operations. A large marine duty disc brake with fully adjustable braking force allows line pull value to be set so that the reel will slip to protect the safe working load of the umbilical. The design houses a 12-pass hydraulic slipring and multi-pass electric slipring to allow for live signals on all umbilical lines while the drum is rotating during deployment.

A portable remote station with 15m long jumper to allows the operator to be located in a safe and practical location when controlling the reeler. Remote and local ESDs will cut pneumatic supply to the reeler drive system, while all maintenance access doors have automatic cut-out switches to protect the personnel.
