The 11-11 Sale That Wasn't

Time flies. Not neccesarily when you're having fun.

The tangled tumbleweed of time has indeed run off hastily as I contend with nasty weather, nasty weather and nasty weather. There were times we would head out, and just five minutes before establishing on finals to a helideck, we would observe a squall line waiting for us over the deck on the weather radar, comfirmed by the helideck radio operator. Those were the mornings when reading the temporary changes in weather on the Aviation Weather Channel always read nasty changes impending the 0300GMT onward, I'd walk out on the tarmac to consider my chances of recovery to the airfield.
Gumusut Kakap and the three generator exhaust stacks visible.

Two cyclones hit the Philippines over the October-early November span, causing widespread squalls over the operational area. Gumusut Kakap being a rather peculiar rig, stands offset from the prevailing winds. Therefore, whenever the winds are not Northeast or Southeast and dangle betwixt the two, the winds carry the hot exhaust gases from their turbine generators onto the deck, resulting in potential power losses to the helicopter in approach to land on deck. The company tries to cater to the client requirements for crew mobilisation by imposing a payload penalty to mitigate the power losses. However, there are times when the stronger winds carry a heap more of these gases in for any weight penalty to be safe for approach and the landing has to be aborted.

It would seem that I have developed a reputation for baulking the landings when wind velocities over the deck have stayed within such prohibited quadrants. Almost as a result, I have had to write show cause letters to Offshore Installation Managers explaining why I refused to land at a particular helideck, or why I delayed a scheduled departure. While I see no direct relationship in any of the company organisational charts linking a line pilot to OIMs, there is a bit of play-ball to engage in occasionally for good corporate relations especially in the spirit of contract renewal. My explanations have never been responded to. That is hardly surprising because when asked to do so, it is a deliberate and duressed move on my part to detail all the aviation factors involved in the decision arrived at by use of the "aircrew decision making process" in crew resource management. Fellas, always use the wood against those who do not belong in trees. Thus, the clamouring for a pilot to pen show cause letters to non aviators has for now, taken a hiatus.
Submarine!!!!

So it was with Gumusut Kakap on 11 November. My copilot and I, upon receiving the manifest and navigation log, read with some interest that it was at the maximum weight for the airfield departure. No weight penalty in consideration for possible changes in wind velocity was applied. True, the Platform Status Report showed wind to be coming in from a very amiable 080 degrees at a breezy 4 knots. But to tempt matters to go wrong with all three gas turbine generators running, a minor pick up in wind strength and a swing into the prohibited quadrant at full all up weight, would make these all look rather ill considered. However, there was no real requirement to apply the weight penalty seeing that on paper, winds were fine and dandy and with that, we set off!

I had already settled on a downwind position at 500 feet, running abeam of Gumusut all ready to make a right hand turn to approach the helideck when the radio call came in from Gumusut: Cap, wind now in prohibited sector at above ten knots. I surrender to Cap lah want to land or not.

In the spirit of Hugh Grant's PM character in Love Actually, I had already decided, "Not to. But we will have to be clever." 

First, I transmitted: "Gumusut R/O, we have not applied the weight penalty for the wind velocity. Never mind, we will make an orbit or two to see if we can make the landing based on the observed wind strength."

I then dutifully executed two orbits around Gumusut. We both knew that we had black and white orders in the carry folder on board the aircraft detailing that a landing cannot be done under the prevailing conditions. We transmitted to Gumusut that we would be returning to base. The passengers were briefed en route to Kota Kinabalu once we were comfortably in the cruise.

After landing, I noted that there was no email from the OIM asking for a show cause letter. I mean, come on!!! Asking for the self explanatory would show the email originator as an imbecile. Instead, the same task was assigned to me for the next day. Rather a cat-and-mouse affair of passive-agression.


Again, my copilot and I perused the flight details. Interesting! A ten percent weight penalty had been imposed! What's this? Wherefore this exercise in caution? The PSR indicated winds from 080 degrees again, at 4 knots. Everything was looking handsome so off we went.

It seemed a nice enough day. As per the Rain Alarm website, actual weather was mild, with en route cloud formations peppered along the flight path. 40 miles inbound to Gumusut the descent was commenced. Again, as the winds were for the right hand seat pilot, I settled there on downwind and at the appropriate distance with the helideck at about my 4:30 by clock code, I executed the turn to finals approach for Gumusut . As I started the run-in to the helideck, a large puff of white fumes emanated from one of the exhaust stacks. I grinned. Any form of smoke, to a helicopter pilot, is the best wind velocity indicator he can ask for. The fumes drifted away from the helideck itself, so I knew that the landing would be free from hot exhaust-incurred power losses. After touchdown, I called in to the radio operator asking where the smoke had come from. That's from the compressors Cap! came the enthused reply. He seemed excited that the landing was made and that his work could proceed without his OIM getting on his back.

And so I radioed back: "Gumusut, next time I fly here under winds in the prohibited sector I will ask for that smoke, alright?"

The terrified reply came in:" Adoi Cap! I cannot do that again!!!!"

Damn!
