Summer 2008

Successful Delivery for SEA CON® (europe) Ltd

SEACON® (europe) Ltd were approached by a leading oil and gas products and services provider in downstream applications with an intriguing challenge. SEA CON® were tasked with providing a connectorized solution for an electro-optic hybrid sub-sea umbilical with some very stringent requirements; one of which was that the optical terminations were to show zero degradation when subjected to deep sea pressures. The lead time for the whole project was subjected to very truncated timescales with the delivery date being of the essence. The customer was anxious that SEA CON® (europe) Ltd take on the challenge as other connector suppliers had declined. The requirement was for 3 field installable connectors, each one containing 76 electrical and 8 optical contacts terminating to 4 separate interfaces along with associated test connectors and jumpers. A series of project feasibility and risk assessment meetings were hastily convened by SEA CON®. The outcome of which was that by utilizing the highly successful MSS and OPTI-CON series of connectors combined within one large field installable connector, the task would be achievable but with no margin for error. Detailed planning, control and all party co-operation would be paramount to the project’s success. Each connector contained over 190 parts, 70% of which required modification, design and manufacture to meet the customer’s requirements. With a purchase order placed on the 1st of November 2007 and a delivery date of 29th of January 2008 this gave SEA CON® just 12 weeks to complete the project. It is with thanks to our design, machine shop, production, purchasing, quality control, stores and the SEA CON® supply chain that the project was delivered ahead of schedule on the 18th January 2008.

New Water Blocked All-Wet Connector

As electronics become more complex and have to withstand ever increasing pressures, SEA CON® has introduced a fully water blocked FAWL connector to its ALL-WET connector range. Developed for a Tow Fish application, SEA CON® Global designed the connector to accommodate accidental removal of the connector head in the unlikely event the Tow Fish was damaged or snagged during operation and not allowing for any water ingress into the Tow Fish electronics housing. Even though the Tow Fish was rated to 2,000 meters water depth, the connectors were tested to approximately 7,000 meters water depth (10,000 psi). The connector achieves this additional capability by incorporating a small water blocked GRE (Glass Reinforced Epoxy) insert into the connector body which acts as a physical water block even if the connector molding is sheared above the metal bulkhead.

WET-CON, Micro WET -CON and Micro WET-CON Split Series Connector Enhancements

As part of our continuous improvement process the SEA CON® Group consistently reviews it’s product range through both customer feedback and internal improvements. It is via these processes that SEA CON® identified a design enhancement to the WET-CON and Micro WET-CON connector ranges. This new design improvement has now been implemented not only across these two connector ranges, but also the new Micro WET-CON Split Series.
The design change is associated with the male pin connectors only and has been introduced to improve and extend the life of the connectors by decreasing the stresses that are applied to the sealing interface between the male contact pin and the sealing rubber around the pin during the connectors mate and de-mate cycles. The newly designed male contact has a ‘lead in’ as part of the contact pin itself which replaces the current rubber ‘lead in’. The introduction of the new pin removes any potential wear to the sealing interface between the male contact pin and the sealing rubber around the pin which may occur with many repeated make and breaks of the connector pairs. The new pin will  maintain the full connector sealing properties and will provide a greater life expectancy of the connectors. The incorporation of this design change to the male pin connectors will not affect the existing female socket connectors currently being used by SEA CON®’s customers and therefore full intermateability will be maintained. In addition, SEA CON® would also like to confirm that pricing will not be affected. This new pin design concept has been fully tested and has been utilized in both the UMATE and SEA-MATE connector ranges for a number of years.
