Steenbank Pilot station

Swath Implementation as from 1st July 2012

• Modus operandi as from 1/7/2012 at “Wandelaar Pilot station”:– Swath vessel “Wandelaar”: main pilot platform

• One tender Swath on pilot station for boarding ops.• One pilot launch (jol) on station for boarding ops. non-

Swath vsls.• One tender Swath transports pilots to/fm Ostend• One pilotboat (classic) transports pilots to/fm Flushing

– Traditional “monohull” Pilotboat as back up– Helicopter pilotage discontinued as from

01/07/2012

• No changes on modus operandi at Steenbank Pilot station

Swath implementation(2)

• Requirements for boarding pilots by Swath• One tender Swath in the proximity of the station vessel

Wandelaar to embark/disembark pilots from/to Swath operable vessels*.

• One tender Swath will transport sea/coastal pilots between shore based pilot station and mv Wandelaar

• Pilot ladder placed at 3,5 m above water level for Swath operable vessels*.

• The speed to embark/disembark pilots must be 10 knots.• Maximum wave / wind conditions to gradually increase.

* See further

Swath implementation(3)

• Requirements for boarding pilots by pilot launch (jol)

• Pilot launch is each time lowered/hoisted from the mv Wandelaar (mother swath).

• All pilots do pilotage via both tender swath and pilot launch.

• Pilot ladder to be placed at 0,3m or 1 foot above water level for “non-Swath operable vessels”.

• Maximum wave / wind for pilot launch operation as before with classic pilot vessel.

• Speed of boarding/disembarking from vessels about 4 knots.

SWATH implementation as from 1st December 2012

• On 1st December 2012 the extended zone at Wandelaar Pilot station will be applicable.

– Approved by IMO• New traffic separation scheme• Extended “precautionary zone” (for pilot boarding area)• Changes to anchorages

– The new procedures from 01-March-2012 with regardto “BTV” (bezwaar tot vervolg) and ”RTA” will be strictlyapplied;

– Boarding operation can not be discontinued.– No restricting RTA’s can be accepted after pilot

boarding.

Present traffic sep. scheme and navigationarrangements at Wandelaar pilot grounds

Larger boarding area with new IMO adopted navigational arrangements as from 1/12/2012

SWATH operability

• Swaths will never board pilots on ships with :– A freeboard or transition height of <2m– Outward turning pilot door– Rubbing strake without 40m interruption for pilot boarding space*

Pilot will board these vessels by “jol”.

• Swaths may board occasionally pilots on ships with :– A freeboard or transition height >2m and <4,5m

AND/OR– Manoeuvring speed on pilot boarding of <10 knots

* See further

SWATH operability

• SWATHS will ALWAYS board pilots on ships :– with freeboard or transition altitude > 4,5m AND – full speed manoeuvres > 10 knots AND– if following secondary conditions are being met:

• Secondary Conditions:Height of “gangway” in case of combination pilotladder/gangway; min. height from lowest platform till waterlevel : 7 meterSide door : (if used) must turn inwards (IMO condition) Side door to be at min.height of 4,5 meter above waterlevel at summer draftRubbing strakes have minimum 40m opening for pilot boarding areaStab.fins retracted or deeper than 4m

Secondary Conditions (1)

Combination gangway/pilot ladder Side Door

Secondary Conditions (2)

In case the ship has fenders / rubbing strakes (protection aside the ship ) a “free area” of 40 m where the Swath pilot launch will board is required

“Stabilisers” to be at least 4 m under the waterlevel or to be retracted

Secondary conditions (3)

Information document on SWATH operability

• Example of the swath operability information form 

1 What is the freeboard at the summer draft

1,1 Less than 2 m YES NO 1,2 Between 2m and 4,5 m YES NO 1,3 Between 4,5m and 9 m YES NO

1,4 More than 9 m YES NO

  If (1,4) is yes is the lowest part of the accommodaton ladder higher than 7m above water? YES NO

2 Is the ship able to maintain a maneuvering speed of minimum 10 knots? YES NO

3 Is the ship fitted with horizontal or vertical fendering YES NO

If (3) is Yes Is there a minimum opening of at least 40 m in the fendering YES NO

4 Is the ship fitted with a pilot door YES NO If (4) is Yes is the pilot door inward turning YES NO

If (4) is Yes What is the height above the summer load line of any fitted pilot door? ……… m

5 Is the ship fitted with non-retractable stabilizing fins YES NO

If (5) is Yes What is the maximum summer draught of your vessel ……… m

If (5) is Yes What is the depth of the non-retractable stablising fins at summer draft ……… m

 

 

• I do not know the Swath operability. How will my vesselbe boarded by the pilot?– The intake info on all vessels will be done about 1h

before entering pilot boarding grounds and questionson actual freeboard and speed will be asked and passed to mv Wandelaar (pilot station) which willdouble check shortly before line-up of vessel(s).

• Can a vessel be NOT-Swath operable incoming and Swath operable on outward voyage (or vice versa)?– Yes. Vessel is loaded inward and freeboard is too

small for Swath operation. Outward vessel is in ballast and freeboard is now sufficient for Swath ops.

– We check actual situation on each voyage.

FAQ’s - Swath operation (1)

• My pilotdoor is too low above the water. Can I still getthe pilot by Swath?– This is possible but only on following conditions:

• aa) your freeboard is less than 9m: if you have a long pilotladder which you can safely rig from ship’s deck till 3,5m above the water, then pilot can board by Swath.

• bb) your freeboard is ≥9m: if you can rig a combinationladder (gangway+pilotladder) and lowest part gangway is min.7m above waterlevel, pilot can board by Swath ( seedrawing).

• Attention: check with ship if a long pilot ladder is on board. Ifnot, ask them to buy one in order to comply with aa) or bb).

FAQ’s - Swath operation (2)

SWATH operation: FAQ’s

• My vessel has no confirmed ok for berth by port auth. Can she start already her transit inward?– No. You must have a “ok”-berth from the port system.

If not vessel will not receive a pilot and should anchor.

• My vessel can enter the port but the RTA lock or coord. point is just too far away in time. The pilot should “loose”some time in the inward transit. Can the vessel start?– No. We calculate the time needed for transit (speed

vessel / tidal stream). Pilot will not board and notloose time underway. Vessel to anchor /drift till right time. Vessel will be called by mv Wandelaar to proceed at the right time for boarding the pilot.

SWATH operation: FAQ’s

• There is storm. Pilot launch does not work and alsoSwaths do not work. How to get a pilot? - Shore based pilotage is started for certain types of

vessels- The vessel must wait at anchor till weather improves- You could ask to send a pilot to a nearby port and

have pilot o/b at dept. of nearby port- Heli is no more available.

• What happens if mv Wandelaar is not on pilot station? – Then we use a classic monohull pilotboat to the pilot

station working with pilot launch (jol) and one tender Swath.
