Incident Response
When activated by a Responsible Party with a covered well MWCC will mobilize its containment system equipment to the designated shorebase location
The RP will direct all activities from quayside to the incident site including offshore installation and operation of equipment
MWCC will provide technical advisors to support the RP’s installation and operation of MWCC’s containment system equipment
MWCC’s containment system has been cited in 119 permits to date

Modular Capture Vessels (MCVs)
Key Specifications
Length ft
Dynamic Positioning DP2
Capture Capacity (BPD) 100,000
Gas Handling (MMCFD) 200,000
Capability Upgrades
Increased Capture Capacity
Enhanced:100k BPD and 200 MMCFD Current: 60k BPD and 120 MMCFD
Decreased Congestion at Site
Subsea flowlines enable tankers to be removed from wellhead site by up to 5,000 ft
Storage capacity of 700,000 barrels, reducing shuttle tanker activity
Quick Disconnect Capability
Turret provides emergency and planned disconnect options
Deployment:
MCVs will be in lightering service and called back to our shorebase in Ingleside to be outfitted as capture vessels if needed for a response. Outfitting the vessel involves installation and integration of a series of modular support frames, which we store and maintain at the shorebase.
Timing: MWCC will study timing during the initial outfitting that is in progress.
Schedule:
The Eagle Texas arrived at the Ingleside shorebase earlier this month and integration has begun. Integration is expected to be completed around year end, after which we will do an SIT and an ORT. The vessel is planned to be ready for service in May/June.

Cap & Flow Operations (ICS)
Cap & Flow Scenario
Cap & flow equipment is needed when the well integrity may not be maintained during an attempt to shut in
Flowback equipment is installed to direct hydrocarbons released from the well to capture vessel(s)
Flowing the well will help allow fluids to be captured until pressure is low enough to shut in or the well is killed by a relief well
