"...standard creek attacks"? I wonder if propper speed boat operation procedures are in place.
Approach oil istallation (flow station, crane barge, house boat) at twin engine MCP, keeping up the speed at 42 kts until within 50' target range. At this point bring one engine back to float idle and start shooting simultanously. Wait for 10 seconds, when fire returned from station is more than what you expect, turn away from target as per approach briefing and go around. If no or little resistance (security agents still in bed, at breakfast, or playing with themselves) both engines to off, board and take over facility.
