The Ucap system includes a range of soft, high strength ROV, or diver, or surface installable and/or removable subsea mud and debris caps available in sizes that to now have ranged from 2”-36” (dia.) with lengths up to 7 meter that is available for purchase.
Surface installed, ROV removable, high strength tear and wear resistant vertical mounted subsea debris cap for protection off and debris ingress prevention in subsea equipment (e.g. drill cutting accumulation in ROV tooling interfaces or funnels). Includes very high load capacity closing feature, and it is released with a single pull (i.e. ROV).
Typical dimension: Dia. 0.3-1.0 meter, height 0.3-1.5 meter; size will be adjusted to user requirement.

Datasheet includes configuration details, features and options.
Surface installed and removable, high strength tear and wear resistant subsea debris, snag point elimination and protection cap for pull-in head assembly (including pull-in in mud and rock dump) that accommodate changing pull-in head curvature. The cap is provided with three level of closing (zip-, velcro- & strap closing).
Surface installed ROV removable, high strength debris and ingress protection for subsea electrical / optical connectors and connector blocks. Single ROV pull to release / remove.
Surface installed, ROV removable subsea debris and protection cap for flowline and umbilical termination heads and connectors. Prevent ingress of mud, sand, silt and other in connector fingers, cavities etc. Protection of coating when pulled along seabed and in rock-dumps. Suitable for termination heads and connectors with or without pull in wire attachment features. Single ROV pull to release / remove.
Surface installed diver removable subsea debris and protection caps for flowline and umbilical termination heads and connectors. Prevent ingress of mud, sand, silt and other in connector fingers, cavities etc. Protection of coating when pulled along seabed and in rock-dumps. Suitable for termination heads with or without pull in wire attachment features.
ROV installed debris cap with the primary function to prevent accumulation of drill cuttings and other debris on a horizontal mounted wing hub clamp blind cap during drilling and completion operations. The secondary function is to provide protection. The cap is installed by the ROV from above lowered down onto the wing hub blind clamp.
Dimensions (W x D x H): 1.03m x 0.42m x 1.24m
Weight (dry): Less than 100 kg
Trapped air passing through splash zone: 0.2 Cu.m.
Since the Ucap is buoyant when passing through the splash zone, it is deployed in an Ubas ROV basket, and secured with a tensioned cargo strap that includes Ustrap release lock. A single ROV pull on the lock release the cap.
Other size Ucaps with similar functions are available on request.
