Overview james.galante1 Rectangle

General Dynamics – Applied Physical Sciences Corp. of Groton, CT (GD-APS) has been tasked by Naval Surface Warfare Center, Carderock Division to provide Engineering Technical Services for the Environmental and Ship Motion Forecasting (ESMF) System. The ESMF program seeks to provide seabased forces with environmental and ship motion forecasting as input to the Common Operation Tactical Picture (COTP), in order to forecast windows of opportunity for inter/intra-ship material and personnel movement.

Under this tasking GD-APS is supporting testing of the At Sea Rearming for VLS (ASRV) concept. This support includes temporarily installing an ESMF system aboard the USNS PILILAAU (T-AKR-304) and a secondary vessel motion measurement unit aboard the USS NITZE (DDG-94). Details for these installations are included in this document. Here is a summary of the installation:

The LMSR ESMF will consist of radar stations mounted on the Forecastle deck and the Ramp A-frame aft (aka king post). There will be a user workstation on the bridge and ESMF components throughout the ship connected by a dedicated fiber network.

The DDG system will consist of only a Ship Motion Senor (SMS) unit.

The LMSR and DDG components will be interconnected via the dedicated ESMF network using an Ethernet cable installed once the ships are moored together.

All required cable penetrations will use existing stuffing tubes.

Although the final mooring plan has not yet been promulgated, the general system layout is shown in Figure 1. It is noted that while the radar positioning provides a full 360o field of view, due to overlap limitations there is a sector on the port side that will not be able to determine coherency (timing) for waves coming from that direction (see Figure 2).

System Description

The ESMF system consists of specialized sensors, a processing suite, and user workstations.

System layouts for the LMSR and the DDG are shown in the following figures with a Size, Weight, and Power (SWaP) table following.

ESMF Sensors

Sensors include wave-sensing radars, a meteorological sensor, and vessel motion sensors.

The planned installation of the sensors for the LMSR AFT ESMF station are shown in Figure 6.

Figure 6: ESMF Sensors

Wave-Sensing Radar

The wave-sensing radars consist of a modified Koden 25kW X-band marine radar.

Modifications include replacing the typical navigation HH-pol antenna with a custom VV-pol antenna, and replacing the transceiver housing to accommodate additional receiver processing to provide coherent (Doppler) capability. Specifications are listed in Table 2.

In addition to the radar mounted on top of the king post a second radar will be installed on the bow using a temporary tower similar to the one shown in Figure 7.

Figure 7: LMSR FWD Radar

Meteorological Sensor

The meteorological sensor provides wind information to the wave-processing algorithm.

It is an ultrasonic instrument which provides true wind speed and direction, barometric pressure, and air temperature.

Ship Motion Sensor

The motion sensor used is the commercially available OxTS RT2502 from Oxford Technical Solutions. The unit will be installed in the AFT enclosure with dual GPS antennas on the A-Frame railing.

Control & Processing Unit(s)

FutureWaves™ control and processing requirements are met by two commercially available, ruggedized embedded PCs, the Cincoze DS-1100. The DS-1100 uses Intel® Core™ i7- 6700, 32 GB DDR4 RAM, with 2x 2TB SATA HDD RAID 0.

Bridge User Workstation

The user workstation planned for the bridged is Dell 5290 laptop or similar system running Windows 10 Professional 64-bit operating system. It uses an Intel Core i7 Quad-Core processor and has 16GB DDR3 RAM. The EMSF User Interface (UI) runs on this processor and provides control of the system.

Secondary Ship Motion System [DDG]

The Secondary SMS is housed in weatherized enclosure (see Figure 4) that is mounted on the secondary vessel (DDG for this test). This subsystem consists of the same SMS used aboard the primary vessel, an Interface Processing Unit (IPU), a network switch, and an isolation power supply. A tablet/laptop can easily be connected for diagnostics if required.

Installation requirements for this are 120VAC/5AMP power, secure mounting of the enclosure, and secure mounting of the antenna tree within 80’ of the enclosure. The antenna tree must also be mounted such that it has a clear view of the sky.

Installation

All required ESMF equipment will be delivered to the USNS PILILAAU prior to installation on three pallets. The pallets are ‘tri-wall’ type bulk containers, see Figure 8, two of which are 62 x 48 x 34” (L x W x H) with a weight of approximately 500#, and one which is 48 x 48 x 34” (L x W x H) with a weight of approximately 400#.

Figure 8: ESMF Shipping Container

The equipment needed atop the king post will be contained in the two containers shown here in Figure 9. These are 55 x 19 x 11” and 75#, and 27 x 27 x 25” and 95#.

The ESMF tower to be used on the forecastle deck is transportable in two canvas bags shown in Figure 10 each weighing 90# with dimensions of 24 x 24 x 60”.

Requested Ship Support for Installation and Demobilization

It is requested that ship support be provided to:

Place ESMF shipping containers on LMSR Main Deck Make top of the A-Frame accessible for personnel prior to arrival for ESMF installation Transport designated equipment to the top of the A-Frame Transport the ESMF tower, equipment enclosure, and forward radar unit to the forecastle deck Transport user work station table and chair to the bridge Assistance in connecting to approved power receptacles Access necessary stuffing tubes, clear cable ways, and re-seal tubes Store shipping containers for the duration of the test

For demobilization:

Make provided ESMF shipping containers available on main deck Transport aft radar from top of king post to the main deck Transport forward components to shipping containers on main deck Transport shipping containers to pier Reseal all stuffing tubes accessed for ESMF

GS-APS will provide Intershield 89 sealing putty for stuffing tubes. Please specify an alternative if necessary.

Power

ESMF required power can be provided with three 110-120VAC receptacles on the LMSR and one aboard the DDG. Each should be dedicated to ESMF if possible with the amperage listed in Table 1: ESMF SWaP. Suggestions for the ESMF processing units aboard the LMSR based upon a ship visit are shown in Figure 12.

Figure 12: Recommended Power Receptacles for ESMF components (LMSR)

Data Cable Runs

GD-APS will run tactical fiber cables as shown in Figure 15 throughout the LMSR for connecting together the ESMF subsystems. Connectors and cables are designed for harsh mechanical and environmental conditions.

The planned cable paths are shown in Figure 14 and Figure 15.

Demobilization

At the completion of the ASRV test and when directed by NSWC-CD or their representative, GD-APS will disassemble the ESMF equipment and place in respective containers. Ship’s assistance is requested in gaining access to the top of the A-Frame. Once ESMF equipment has been de-rigged, ship’s assistance is also requested in re-sealing any stuffing tubes and for transporting equipment down from the A-Frame and aft from the forecastle deck.
